Summary | 0031854: General fuse generates shape looks bad | ||||
Description | The upload file general-fuse-invalid.brep contains two shape, the general result looks bad from the result picture. | ||||
Tags | No tags attached. | ||||

general-fuse-invalid.brep (718,452 bytes) |
|
general-fuse-2shapes.png (16,663 bytes) |
|
general-fuse-2shapes-invalid.png (17,030 bytes) |
|
Also the boolean operation fails between these two objects. Anyway, general fuse should work. |
|
Dear Eugeny, could you check your latest patches? |
|
The second shape in the compound is invalid in terms of bopcheck.restore general-fuse-invalid.brep s explode s bopcheck s_2 explode s_2 f don s_2_1 How was this shape created? |

face.png (9,922 bytes) |
|
The shape was created via occt library, such as primitive + boolean + loft + sweep, etc. |
|
The problematic face is shown on the picture it has obvious self-intersection of its boundaries. Looking at the surface under this face I have seen self-intersection of the surface. Such shapes are problematic for the majority of OCCT algorithms. You should avoid creating such geometries while working with OCCT. |
|
So do you mean we should fix the shapes before occt algorithm perform? Anyway, it's ok for me. Thanks for your clarification. |
|
Dear bugmaster, this bug can be closed. |
